Description
FIELD OF THE INVENTION
[0001] The present invention relates to flat panel displays, and in
particular to a flat panel display having a function button on the
back.
BACKGROUND
[0002] Generally, a flat panel display has several function buttons
on the front thereof, for controlling characteristics of images
shown on a screen of the flat panel display such as luminance and
contrast ratio.
[0003] FIG. 7 is an exploded, isometric view of a typical flat
panel display. The flat panel display 100 comprises a front housing
part 101, a rear housing part (not shown), a display panel 102, a
circuit board (not shown) electrically connected to the display
panel 102, and a button module 103.
[0004] The display panel 102 is secured by the front housing part
101 and the rear housing part. A plurality of button through holes
1011 and an indication light 1012 are provided at a lower section
of the front housing part 101. The indication light 1012 is for
indicating a status of operation of the flat panel display 100 to a
user. The button module 103 is sandwiched between the front housing
part 101 and the display panel 102. The button module 103 comprises
several function buttons 1031, a button circuit board 1032 with a
button circuit, and a securing element 1033. The button circuit
board 1032 and the function buttons 1031 are secured on the front
housing part 101 by the securing element 1033. The function buttons
1031 are arranged in positions corresponding to the button through
holes 1011, and penetrate through the button through holes 1011
once the flat display panel 100 is assembled. The button module 103
is electrically connected to the circuit board of the display 102
via a connecting wire (not shown). The user can control the display
characteristics of the flat panel display 100 by operating the
function buttons 1031.
[0005] Because the button module 103 is designed as a separate
unit, the connecting wire for connecting the circuit board of the
display panel 102 with the button module 103 is necessary. The
connecting wire adds to the complexity of the assembly and raises
the cost of the flat panel display 100.
[0006] Accordingly, what is needed is a relatively simple and
inexpensive flat panel display.
SUMMARY
[0007] A flat panel display includes a display panel, a circuit
board, a housing, and a button circuit. The circuit board is
electrically connected to the display panel. The housing includes a
front housing part, and a rear housing part with an integral
function button, wherein the display panel and the circuit board
are secured by the front housing part and the rear housing part.
The button circuit is provided on the circuit board at a position
corresponding to the function button.
[0008] The functional button of the flat panel display
above-mentioned is cantilevered, and the function button is
arranged at a right section of the rear housing part, or at a left
section of the rear housing part. The flat panel display further
includes an indication light and a guiding symbol. The indication
light is provided on the front housing part at a position
corresponding to the function button, and the guiding symbol is
formed on the front housing part at the position opposite to the
function button. The flat panel display further includes a metal
shield covering the circuit board.
[0009] Compared to conventional flat panel displays, the function
buttons are integrally formed on the rear housing part, and a
connecting wire between a button circuit and a main circuit board
is eliminated. The process of assembly of the flat panel display is
simplified, and costs are reduced.
[0010] A detailed description of various embodiments is provided
below with reference to the accompanying drawings.

and
[0018] FIG. 7 is an exploded, isometric view of a flat panel
display of the prior art.
DETAILED DESCRIPTION OF EMBODIMENTS
[0019] Referring to FIG. 1 through FIG. 6, a flat panel display 1
comprises a display panel 10, a circuit board 20, a housing 30, and
a metal shield 40. The circuit board 20 is electrically connected
to the display panel 10. The housing 30 comprises a front housing
part 32 and a rear housing part 34. The display panel 10 and the
circuit board 20 are secured by the front housing part 32 and the
rear housing part 34. The metal shield 40 is for securing and
covering the circuit board 20 and for shielding electromagnetic
interference (EMI).
[0020] Three cantilevered function buttons 342 are integrally
formed at a right side section of the rear housing part 34. A
plurality of slits is defined in the rear housing part 34 around
the function buttons 342, thereby providing the function buttons
342 with elasticity. A button circuit 22 is formed on the circuit
board 20 at a position corresponding to the function buttons
342.
[0021] Three indication lights 322 and three guiding symbols are
formed at a right side section of the front housing part 32, at
positions respectively corresponding to the function buttons 342.
The indication lights 322 are used for indicating respective
statuses of the flat panel display 1 to a user, and the guiding
symbols are used for guiding the user to press a corresponding
desired one of the function buttons 342 on the rear housing part
34.
[0022] Because the function buttons 342 of the flat panel display 1
are integrated with the rear housing part 34, the flat panel
display 1 is relatively simple in construction and correspondingly
inexpensive. In particular, unlike in comparable prior art, the
flat panel display 1 does not need a connecting wire for connecting
the button circuit 22 to the circuit board 20. The process of
assembly of the flat panel display 1 is simplified, and costs are
reduced.
[0023] Assembly of the flat panel display 1 is as follows. Firstly,
the display panel 10 is electrically connected to the circuit board
20. Secondly, the metal shield 40 is arranged on the circuit board
20 as a shelter. Finally, the display panel 10, circuit board 20,
and the metal shield 40 are secured by the front housing part 32
and the rear housing part 34.
[0024] The flat panel display 1 may have alternative embodiments to
those described above. For example, the function buttons 342 can be
formed at a left side section of the rear housing part 34 (as shown
in FIG. 7), or at an upper or a lower section of the rear housing
part 34. In these embodiments, the button circuit 22 on the circuit
board 20 is positioned according to the positions of the function
buttons 342. In other examples, the function buttons 342 may be
positioned at two or more of the right side, left side, upper and
lower sections of the rear housing part 34. In these embodiments,
there are two or more corresponding button circuits 22 on the
circuit board 20, which are positioned according to the positions
of the function buttons 342. In still other examples, there may be
only one or two function buttons 342; or there may be four or more
function buttons 342.
[0025] While the invention has been described by way of example and
in terms of the preferred embodiments, it is to be understood that
the invention is not limited thereto. To the contrary, the above
description is intended to also cover various modifications and
similar arrangements as would be apparent to those skilled in the
art. Therefore, the scope of the appended claims should be accorded
the broadest interpretation so as to encompass all such
modifications and similar arrangements.
